Product Overview


The Trilennium® Handset Thumbturn is an essential piece in your Trilennium Handset. Once the thumbturn is turned, the action transfers the motion of the thumbturn through to the lock system, locking the 3 bolts into place. With Trilennium, you’re not only getting 3x the security and 3x the strength, you’re also receiving the benefit of the user-friendly application with just the simple turn of the handle.

To order a replacement thumbturn kit, select from the options for both color and style. Not all styles are available in all colors.
